The top seed was in an unforgiving mood on Wednesday and the 21-year-old had no answers to the Spaniard’s relentless ball striking as he blitzed his way into round three with a 6-2 6-1 win in less than an hour.

Playing under the roof at the Qizhong Stadium, Donaldson held his own for the opening four games but soon fell away, with Nadal at his ruthless best.

Up next for the 16-time Grand Slam champion is a familiar foe in the form on Fabio Fognini, who has troubled Nadal in the past.

The world No. 28 has beaten him on three occasions and set up a 13th meeting after beating France’s Lucas Pouille 7-6 (9-7) 6-3.

Nadal got off to a sharp start on serve and looked fired up but Donaldson wasn’t giving much away either and didn’t drop a point in his opening two service games.

That all changed next time the world No. 56 stepped up to the line, as Nadal crafted two break point chances and converted the second for a 4-2 lead.
